IMPRQVEMENT IN BURNING PETROLEUM AND OTHER HYDRDCARBON OILS.

The Schedule referred to in these LattersPat'ent and making part of the same To all whom it may concern: 7

Be it known that I, Luc us E. 'lnnnsnnnn, of Warren, in the county of -Worcester, in the State of Massachusetts, have invented certain Improvements in Apparatus for Burning Petroleum and other Hydrocarbon Oils, for the generating of heat and steam, and the reduction of ores, &c., of which the following is a full and exact description, reference being bad to the accompanying drawings making part of this specificaiion, in which- .Jsigure 1 represents a transverse sectional view 0: the fire-box of a steam-boilerhaving my improvements applied thereto, as also of the oil and water-chambers for feeding the fire. I

I igure 2 represents a similar view, taken longitudinally through the boiler, a portion being broken ofi Figure 3 represents the application of-my improvements to a stove for heating purposes, a, part of the cylinder being removed to show the arrangement of. the apparatus.

Figure 4 represents an enlarged view, in perspective, of my improved apparatus, as detached from thestove, furnace, or boiler, the reservoirs with which it is connected being shown in section.

Figure 5 represents a plan of the fire-pot, as detache'd from the stove, and its covers, and

Figure 7 represents an end view of the fire-pot, together with its covers. orblowers, as also tl'ie'iiiachinery for operating the same, and

.Figure'S a detached view, in perspective. of one of the blowers or covers.

My invention relates to that class of stoves, furnaces for smelting ores, glass, &c., as of furnaces for generating steam, 860., in whicl'i ietrolcum and its products, and other hydrocarbons, are used as fuel.

For such purposes these oils and their products have heretofore been used, and in two distinct ways, one of these methods being by generating avapor and burning it in that form as you would gas, and the other by the direct combustionof the oil.

The first method is necessarily expensive, as it requires costly and compiicatedmachinery as an adjunct, while the second has been so far (comparatively speaking) a failure, arising principally from the imperfect modes adopted for burning it, thereby involving great My presentimprovements are designed to remedy that defect; and it consists- First, in combining the vapors of water or steam with the vapors of thcpetroleum, as generated, while in the act ofbcing mixed with air-and burnt, which I find of vast service and utility, as it renders the combnstion perfect, the 'steamwapor pfrobahly expanding the denser vapors of the oil, and thereby materially assisting in the more intimately commingling of the air with the hydrocarbon vapors, and thus insuring its combustion.

Secondly, in combining with the chambers used in the fire-pot for the generating of the vapors of water .and of oil, a series of pipes or fines, so arranged as to ers, an air-conduit, which mayor may not be connected with a flux-blower, whereby a column, or jet or jets of air can benprojected through them into the flame of the burning oil to aid in its more perfect combustion. Fifthly, in the combination of an oil and water-reservoir, either combincd'or-detached, and their respective pipes, with the 'severalchambers of the fire-pot, for their relative and proper supply of water and oil.

i 'Sixthly,.iu the combination, with the oil-chamber of the fire-pot, of a drip-vessel to receive suchoilas may happen to be in excess of its demand for consumption.

To enable others skilled in the art to make, construct, and use my invention, I 'will now proceed to describe its parts in detail, omitting a particular description of such parts of a stove, furnace, or steamhoilei: as are common to others, and unnecessary for the full understanding of my invention In the drawings my improvements are represented as applied, in'figs. 1 and'2, to a steam-boiler, in which the shell A, fire-box B, and fines Gare constructed in the usual manner,

Into thefirc-space or box B is arranged my improved fire-pot D, which is made to rest on projections a attached to the inner sides of the fire-box. Thus arranged-it is removable zit-pleasure.

The fire-pot is represented as being of an ovoid form, but it may be made of anyconvenicut or suitable form, and consists of a trough or rat divided into two oomp'artments, c andj, the central one, a, being intended to be filled with water,'whilc the outer one, f, (and which, in this casc, entirelysurrounds the other,)'is

intended to be partially filled with water, and then supplied witlFthe-petroleum or other suitable hydrocarbon oil, which isto -constitute the fuel for running the engine. Here it maybe observed that the reason for placing the water in the central vat or chamber is, that it may be subjected to the action of the burning oil, so as to generate steam, which, mixing with the vapors of oil generated alongside, and with tlieair supplied through the. fines 9, so expands or dilutes the vapors of oil, as it were, as to enable them to bc consumcd entirely withoutemission of smoke. It will,

therefore, be apparent that any number of chambers containing water and of chambers containing oil may be used in the same fire-pot, when arranged alternately, as may be deemed advisable, consistent with a proper supply of air, which, for the perfect combustion .of the oil, should pass up in flues or' air-conduits g, through the oil-chambe'r-f, as shown in figs. '2, 3, 4, 5, and 6.

Immediatelyover the fire-pot 1) is, arranged a sliding coveror blower, H, as shown in figs. l and 2, or of two covers, as shown'in'fig. 6, which, by means of a screw-rod, I, attached to a bracket, 1', on the side of the fire-pot, maybe made to extend either partially or entirely over the fire, according as it is required to regulate the size of the blaze, or to extinguish it entirely,the screw-rod I, for this purpose, being provided with a hand-wheel, j, with which to operate it.

Through the covers H, in a longitudinal direction, is formed an air-conduit, d, from the inner face of which emanate a number of jets, through which air is projeetedon the outside of the flame, to aid in its more perfect combustion. If deemed advisable or desirable, a force-blast may be used in connection with this conduit.

I The air-fines it will be observed, are made to pass entirely through the fire-pot, t-hus'communieatingwith the open air in the lower part of the fire-box proper, and may, if desired, be used in'connec-tion with a fan-- blower or force-blast to promote combustion, if desired.

The oiLcha-mber f of the fire-pot l) is made to com munica'te with two reservoirs by means of two pipes,

'm and n, the one reservoir, M, containing the oil in'-- tended for the fuel of the fire, and the other, N, water. Each of these pipes is provided with stop-cocks, by means of which the flow, either of water or oil, is regulated;

From the pipe m a liranclr pipe, o, is led, and made to communicate withthe central chamber e, in which the vapors of water are generated. This pipe is also provided with a stop-cock to shut off or regulate the flow.

The operation is substantially as follows:

The reservoirs M and N. are first filled, the one, M, with oil, and'the other, N, with water. As illustrated in the drawing, the oil-reservoir M is arranged in the inside of the water one, N, in order'to protect the oil from the heat, althoughit need not, necessarily, be soarranged for the purposes of my present improvement. 'lhus prepared,the cock 1) of the pipe or is then turned so as partially to fill the oil-vat f of the fire-pot D with water, and again closed, when the oil-cock q of the pipe in is opened, so as to allow the oil to pass into the chamber f at the bottom, whence it passes to the surface of the water because of the superior specific gravity of the latter, where'it floats, and, being there ignited, is burnt, the necessary air for its consumption passing up through the fines g. Meanwhile, the cock s has also been turned-so as to admit water into the central chamber '0, for the generation of the steam-va-- pors before referred to. Once the whole has been started, eaeh' cock is regulated so as to admit the necessary quantity of water and of oil to each of the compartments of the, fire-pot, and no more; but should there'be a greater flow-ofoil than can be burnt advantageously, the excess-is allowed to escape at the top, by means of apipe, k,-iuto 'a'closed drip-pan, Z, whence it may be taken at intervals and returned to the reservoir M. This waste,,however, as. far as possible, should be regulated by means of the stop-cock q.

Fromwhat has been said, it will be clear that the apparatus described can be appliedas well to the heating of houses by stoves or furnaces as to the generating of steam, and also to the reduction of ores, to glass-furnaces, and to a great variety of other useful purposes.

Having thus described my invention,
